Integrating earthen floor, foundation, rocket mass heater for a yurt

I have this crazy idea that just might work.....

The idea is to have a heated earthen floor for my yurt.
Thinking that I'd like to put the yurt on the ground instead of the typical deck and heating the floor with a RMH.
Wondering if the idea is feasible. Please poke holes in my plan!

I'm not sure what would be entailed with heating the floor with the rocket mass stove. There is definitely someone on Permies who can chime in on that, but the earthen floor would need to be substantially thick I would think. The insulation would be better up above your drain layer on the floor design as would the waterproof membrane if you even need one. In the current location, the insulation would either act as the moisture barrier or take on moisture and lose its insulation value.

I think an easier alternative for both function and design would be to layer: drainage layer (i.e. gravel), moisture barrier (if needed), insulation (bottles, pumice, poly-iso), earthen floor, and then put a normal bench RMH inside to heat the yurt. I imagine you will want a place to sleep or sit so the bench isn't really any extra work and you wont risk losing heat as much to the ground. If you have cheap access to pumice or scoria you can use it for both drainage and insulation.

Sounds awesome, post photos if you pull the trigger on this project!

Toxic gick warning for some of their finishing techniques, but they do have an in ground rmh.

These people did what you describe a few years ago, and it apparently worked well: rocket mass floor heater -- finally completed and it works!
